: I was just checking inventory at Federal Mogul
: on the TRW forged pistons that we have left
: for slant 6 engines and thought I would
: share it with you. The results are as
: follows: L2125F Std.- 6 pistons
: L2125F .030"- 41 pistons
:
: L2502F Std.- 56 pistons(2.2L with 198 rods)
: L2502F 100mm- 4 pistons

: OHHHH Charlie: bust out the check book

:
: These are FORGED Pistons at a reasonable price.
: I have used both types and they are strong
: units. (also a bit heavy weight wise)
: The 2125F uses the 6.700 225 con rod, the 2502
: must be used with the 7.001 long 198 con
: rod.
: I show this piston in my stroking article.
: DD

: where would your compression be at if you used
: a 2.2 liter or one of the vw 88mm pistons
: with the 6.700 rod and would milling the
: block and the head get you back up to a 8 to
: 1 cp ratio? could this be done?

: Well Andrew, I can tell you this much. Mine
: with the 198 rods came up with a deck height
: of -.028" on a stock uncut deck. The
: 6.7 rod is about .300" shorter so
: theoretically, deck height would be
: -.328". You could probably get away
: with decking the block .125" which
: would get you back to about -.200" Chop
: about .090" off the head, and add an
: -.060" overbore, and theoretically you
: would be just about right. (This message not
: to be used for any purpose other than it's
: original intent)

: Do the 225 pistons have enough material to be
: machined down far enough to be used with the
: 198 rods? I am looking for about 12 to 1
: compression and I have a set of 198 rods.

: this may not be a feasable alternative to all
: parties: instead of doing 198 rods and 2.2
: pistons i decked the block .145 the
: surfacing machine was much closer than the
: rods and pistons at the time.

: No, there is not enough material on the 225
: piston to do that.
: Go take a look at the "Stroking the
: SL6" article I have posted in the
: article section, the "flat top"
: 2502 2.2 Forged piston will give you mid 11
: to 1 CR and then you could mill the head /
: block for the rest.

: Will a 1.78 intake and 1.50 exhaust valves fit
: in a .045 oversized bore? THANKS! Darrin
